Hi all, New to this forum. I just wanted to ask if anyone noticed that in the episode "His Last Vow" (Season 3 Episode 3), when Sherlock meets with Charles Magnussen, the "Napoleon of Blackmail", Magnussen can be seen "scanning" Sherlock's pressure points, and among the rather extensive (and repetitive) list, one thing stands out — "Redbeard". Was this a sneaky easter egg that the creators snuck into an early episode of Sherlock? Sorry if this is common knowledge — just kinda got excited when watching reruns to see such an important plot element in "The Final Problem" show up in an older episode. :P Cheers, L
